Battery analysis for your Steyr S 9S18

Quick answer Depending on the equipment, your vehicle uses one of these two main batteries. The most common option is ordinary lead-acid 130 Ah (514×175×210 mm): we recommend VARTA J10. Other units use ordinary lead-acid 140 Ah (513×189×223 mm): VARTA K8. Before buying, check the Ah on your current battery's label or measure its length.

Based on the batteries we found for your vehicle, our experts help you pick the right one.

📋 What we found

For your Steyr S 9S18 we found 10 compatible batteries. This list includes 2 AGM or EFB batteries and 8 conventional batteries.

📏 Battery size

The list contains batteries in different sizes or capacities (Ah). In many cases both variants fit, but it's worth checking your compartment dimensions and the Ah of your original battery before buying. Choose the one with the same dimensions as your current battery: a bigger one may not fit the compartment or the hold-down. If several match your size, the higher capacity gives more headroom for cold starts.

Before you buy: check 3 key points

Although the batteries shown are sourced from information provided by manufacturers, we recommend checking on your current battery:

Dimensions (length × width × height, including terminals and protrusions)
The dimensions shown are the maximum of the battery and include the height of the terminals, small ridges at the base and any lateral protrusions. Measure your current battery completely, from edge to edge. The new one must be the same size or slightly smaller — never larger, it would not fit in the housing.
Positive terminal (left or right viewed from the front — check the battery photo carefully)
Stand facing the battery, with the manufacturer's label facing you and the terminals on top. Locate the terminal marked with +: if it is on your right, it is "positive right"; if it is on your left, it is "positive left". Do not rely on how the battery is mounted in the car — the position is always measured looking only at the battery itself.
Technology (AGM, EFB or conventional — the same as your current battery or higher)
Depending on the manufacturer, the same technology may be labelled differently: AGM may also appear as VRLA, AGM Start-Stop or AGM Deep Cycle. EFB may appear as EF, EFB+ or Enhanced Flooded Battery. Conventional may appear as SLI, Lead-Acid, Wet or Standard. If your vehicle has Start-Stop, the battery must be AGM or EFB — never conventional.

If you have any questions, just ask us and we'll be glad to advise you with no obligation.

AGM / EFB batteries

AGM or EFB technology batteries: more charge cycles, faster recovery and a longer life than a conventional battery.
